PLEASE HELP! When can i check if im pregnant?

Ill keep it simple. My S/O came inside me on the 3rd or 4th of January and my period was supposed to come on the 5th. I spotted for about 2 days and then it stopped. I tested around the 11th and it was negative but it may have been too soon? Ugh idk!

Im stressed and feel extra moody. When is the soonest i could possibly test that. Do i have to wait for another missed period?

Please help me ladies! I dont wanna waste anymore tests and have them be negative bc i tested too soon.

Trust me i looked online and all the sources say diffrent things
